Overview
Brief Summary
The purpose of this study is to assess the pharmacokinetic (PK) properties, safety and tolerability following a single dose administration of GOPRELTO® or NUMBRINO™ as an anesthetic for diagnostic procedures and surgeries on or through the mucous membranes of the nasal cavities in pediatric adolescent subjects.
Detailed Description
GOPRELTO® and NUMBRINO™ (cocaine hydrochloride nasal solution, 4%) are approved anesthetic products in adults. The purpose of this study is to assess the pharmacokinetic (PK) properties, safety, tolerability, and dosing of GOPRELTO® and NUMBRINO™ each as an anesthetic for diagnostic procedures and surgeries on or through the mucous membranes of the nasal cavities in pediatric adolescent subjects. The primary objectives for each treatment of the study are: * To assess the safety and tolerability of GOPRELTO® and NUMBRINO™ nasal solution in pediatric adolescent subjects as an anesthetic for diagnostic procedures and surgeries on or through the mucous membranes of the nasal cavities, respectively. * To evaluate the PK properties and define the dosing for GOPRELTO® and NUMBRINO™ nasal solution, respectively, in pediatric adolescent subjects as an anesthetic for diagnostic procedures and surgeries on or through the mucous membranes of the nasal cavities.

- •Has a history of abuse of controlled substances, nasal or otherwise.
- •Has a positive test result for drugs of abuse at the Screening Visit: amphetamines, barbiturates, cannabinoids, cocaine metabolites, opiates, and oxycodone via a urine test. Alcohol is prohibited within 24 hours prior to Treatment Day
- •Is a pregnant female or nursing mother or has a positive urine pregnancy test at the Screening Visit or on Treatment Day
- •Use of any serotonin-norepinephrine reuptake inhibitors/selective serotonin reuptake inhibitors (SNRIs/SSRIs) up to 14 days prior to the Screening Visit or has a need to use these drugs at any time throughout the duration of the study.
- •Use of monoamine oxidase inhibitor (MAO) drugs up to 14 days prior to the Screening Visit or has a need to use these drugs at any time throughout the duration of the study.
